I have a 2013 lx with 151k, 2 years ago I had a ac leak took it to the dealership found the High Schrader valve leaking. They replaced it. Vacuumed and pressureed tested it and it was good. Last week I took out from storage and no AC. I took it to the shop and they filled it. 2 days later no ac. Filled it again and woke up today with no ac. So I took it to a professional shop specialized on ac systems. They did the whole 9 yards including dye they couldn't find a leak.

Even the pro shop may not have fully investigated leaks in the rear system. You have to do some disassembly back there to see all the fittings and components. Really ditto for the dash components as well. Given the symptoms of needing almost continuous refill, there’s a leak somewhere. Likely a corroded connection in the rear is my guess.

They told me if it leaks, just bring it back to see where the leak is. Thank God the evaporator is working and no leaks there. They scanned the lines and evaporator with gas leak detector. Im having a feeling its the o-rings for the rear ac.
Here’s a thread on the fairly common leak at the rear AC from corroded aluminum connectors under the rear of the vehicle. There are other threads on this too.

Common 200 series A/C leak?
Then yes it’s probably AC system oil and that is likely a leak source. If you have a cool box in your console those lines run up into it. If not it’s possible that’s a joint before the lines run back to the rear AC. The leak at the rear is somewhat common in vehicles with corrosion. From memory...

The rear ac fittings are aluminum and corrode in a road salt environment like Detroit. Could easily have a pin hole leak. Take it to a shop that specializes in automotive AC and they will find the leak.

That's where I took it. Once they vacuumed and pressureed the system for 2 hours everything seems fine. I went last night with my uv light to check the rear lines. I didn't see no ac dye leaking.
I recently dealt with a slew of leaks on my 2015, started at ~113k miles.
One was supposedly rear line going to the rear evaporator that was replaced, then leaking o-rings under the hood, then yet some other o-rings somewhere under the body "in the middle". This took 3 visits to 2 dealers. The first was handled under extended warranty (that I foolishly bought it, not worth it, it was the only claim), but it leaked within a month again. 2nd was free repair as a courtesy from another dealer who took pity on me (I was away from home), 3rd from the same dealer who charged me $300 this time for evac/recharge only - so I lucked out here, the total cost was like $500 (with the warranty deductible and the $100 the first dealer has the gall to charge for new schrader valves I requested). Two months later now and the A/C seems to be holding up, but I bit disappointed with the extent of the "leakage".
